JOSEPH SHAOKLETON,l OF NEW YORK, N. Y.

SPECIFICATIONforming part of Letters Patent No. 374,989, dated November 2,9, 1887.

Application led April 5, 1887. Serial No. 233,815. (No model.)

To all whom it may concern.-

-Be it known that I, JOSEPH SHACKLETON, a citizen of the United` States, residing at New York, in the county and State of New York, have invented new and 'useful Improvements in Conduits or Hose, of which the following is a specification. e

'This invention relates to improvements in conduits or hose, as set forthfin the following specification and claim, and illustrated in the accompanying'drawings, in whichy Figure l is a longitudinal sectional View of a hose or conduit. Fig. 2 is a' section in the plane x w, Fig.l l.

'Similar letters indicate corresponding parts.

In the drawings the hose or conduit is shown as applied to two railroad-cars, where such hose can be used for conveying heat to such cars. Applications of the hose to other" purposes canv of course be made.

. In the drawings, the letters A indicate the upper parlsof the end walls of ytwo cars.

B B are the car-roofs. Through the cars extend pipes or conduits C. The pipes C may be fixed to the ears at any suitable place and in any suitable' manner.

-To the tubes O are connected pipes E by suitable means, such as screw-threads. The pipes E are provided with stuffing-boxes F. Through the stuffing-boxesF pass pipes G. Shoulders H may be provided to limit the motion of the pipes G in the stufingboxes F.

To the pipes G is connected a flexible or vThe hose I is connected to the pipes G by suitable means, su ch as by slipping or clamping t-he ends of the hose'I into engagement With the pipes G.

To prevent' the hose I from sagging, said hose is provided with spiral springs K L. The spring K is applied to the hose at its exterior. The spring L is applied to the hose at its interior. The hose I is spirally corrugated, and

the springs K L are seated inthe spiral corrugations of the hose I. The flexible hose I is thus prevented from sagging, and consequently material such'as water or other iinid is not apt to stand in the hose I. As such standing fluid 'may at times freeze in the hose,

injury to the hose may result. By preventing sagging of the hose I no duid can stand in the hose I when the hose is applied as shown in the drawings. The springs K L do not destroy the flexibility of the hose I, so that said hose is still free to yield to the motions of the cars. A

The pipes G, sliding in the stuffing-boxes F,

'also facilitate the yielding of the hose I to the motions of the cars. A stop-cock, D, may be applied passage through the pipes C.

to close the In order to make the hose I readily detachable from the sliding tubes or pipes G, thev l hoseIis shown as provided with tubes or tubular Shanks M, having screws N .V The screws .N are shown inthe form of female couplingscrews engaging screw-nipples at the ends'of the sliding tubes or pipes G.

4What I claim as new, and desire to secure by Letters Patent, is i The combination of the tubes E, provided with the stufngboxes F, the pipes G, slidable
